What is the name of J.K. Rowling’s pen name for crime novels?

J.K. Rowling used the pen name Robert Galbraith for her crime novels.

The name first appeared on The Cuckoo’s Calling, published in 2013. The book introduced private investigator Cormoran Strike and his temporary partner Robin Ellacott. Rowling later continued the series with additional novels under the same name.

The pseudonym was not initially publicized as Rowling’s identity. Her authorship was revealed after a legal and media investigation in 2013. Rowling then confirmed that she had written the novel, while continuing to use Robert Galbraith as the series’ author name.

Robert Galbraith is therefore not a separate writer with an unrelated bibliography. The name distinguishes Rowling’s adult detective fiction from her Harry Potter books and from her later novels published under her own name.
